ELECTRIC WATER-HEATER.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed October 14, 1916. Serial No. 125,676.

To all whom it may concern.

Be it known that I, EMIL STRANszKY, a citizen of the United States,residing at New York. New Yorkcounty, and State of New York, haveinvented and discovered certain new and useful Improvements in ElectricWater-Heaters. of which the following is a specification.

The present invention relates to electric water heaters and consists inthe combinations and arrangements of parts hereinafter described andparticularly set forth in the accompanying claims.

The invention has for its purpose to provide an electric heater forwater systems, wherein the heated. water is adapted for use at a distantstation, and in which a local supply of water is maintained constantlyheated and for use at the immediate heating station.

The invention has for its further purpose to construct an electric waterheater having a common control for the circuit closer and flow of water,and with a variable control for the local supply; and in which theapparatus as a whole constitutes a unitary structure adapted to bereadily set up in present installed water supply systems.

The invention is shown by way of illustration in the accompanyingdrawings, wherein Figure 1 is a central sectional view of the heater,with the wiring circuit in diagram.

Fig. 2 a horizontal sectional View taken on the line 22 of Fig. 1, and

Fig. 3 a similar view taken on the line 3-3 thereof.

Referring to the construction in detail the apparatus consists ofacylindrical vessel 1 having a section 5 detachably mounted thereon, andprovided with a pair of head plates 6 and 7 forming a water receivingchamber 8, a water discharging chamber 9, and an intermediate airheating chamber 9'. A pipe 8 connects the receiving chamber 8 with thesource of water supply.

A partition plate 10 is mounted in the cylinder section 5 to form anauxiliary hot water supply and discharging chamber 11 that communicateswith the main discharging chamber 9 through the apertures 12 and 13formed in said partition 10, as shown in Fig. 2. Said openings 12 and 13are of relatively difi'erent sizes to the end that difierent flows ofwater may enter said auxiliary discharging chamber, to be furtherdescribed.

A plurality of tubes 14 are located in the heating chamber 9 and aresecured at their respective ends to the head plates 6 and 7 and each ofsaid tubes is provided with a covering of insulation 15, of any suitablematerial. An electrical resistance coil 16 is wound on the insulation ofeach tube and the several resistance coils are connected in parallelwith the circuit conductors 17 and 18 from the source of electricalenergy 19; and a condenser 20 is provided to prevent sparking at theswitch, as will be understood. 4

A water discharging pipe 21 leads from the main water chamber 9 to adistant station, and the flow of Water therethrough is controlled by avalve 22 that is mounted on the shaft or stem 23 journaled in suitablebearings in the cylinder section 5 and the partition plate 10. Therotary valve 22 is formed with an annular flange 24 fitting closelyagainst the inner surface of the wall 5, and said flange is constructedwith an in-set portion 25 forming an opening adapted to register withthe pipe 21. An aperture 26 is formed in the disk portion of the valveto register with either of the apertures 12 or 1-3 of the partitionplate 10 and govern the flow of water into the auxiliary chamber 11; anda faucet 27 is provided for drawing off the heated water from saidchamber, as shown. The circuit closing device for the apparatus consistsof a block of insulation 28 suitably secured to an extended portion 29of the cylinder part 5, and. a plurality of pins or contact members 30are secured in the block 28 and are connected in pairs with theconductor wires 17 and 18, as indicated at 31, whereby a circuit will beclosed through all the resistance coils accordingly as the water isdischarged through either the pipe 21, or into the chamber 11 throughthe openings 12 or 13.

The switch per se consists of a contact piece 32 that is mounted on thesquare and tubular stem 33, having loose engagement with the squared end34: of the valve stem 28, and a knob or hand-turning piece 35 isprovided for turning the switch to close a circuit through the coils andregulate the flow of hot water. The hand-turning piece chamber, anoutlet 35 has slight freedom bf axial movement,

from the spirit of my invention, and therefore l do not wish to belimited to those features except as required by the claims.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent, is:

l. lln an electric water heater, the combination of a vessel having awater receiving chamber. and a water discharging chamber, a partitionwithin the water discharging chamber providing an auxiliary dischargingch-amber communicating with the main discharging chamber, a waterheating tube in the vessel connecting said water receiving anddischarging chambers respectively, a coil of resistance wire around saidtube, a circuit closing device for the resistance coil, a waterdischarge pipe leading from the main discharging chamber, an outlet pipefor said auxiliary water chamber, a rotatable valve for said dischargepipe and the passage to the auxiliary discharging chamber, and a commoncontrolling device for said valve and the circuit closer, substantiallyas set liorth.

2 in an electric water heater, the combination of a vessel having awater receiving chamber and a water discharging chamber, a partition insaid discharging chamber providing an auxiliary water dischargingchamber communicating with the main discharging pipe for said auxiliarydischarging chamber, a water heating tube in the vessel connecting saidreceiving and discharging chambers respectively, a coil of resistancewire around said tube, a circuit closing devicei'or the resistance coil,a water discharge pipe leading from the main discharging chamber, arotatable valve comprising a flanged plate mounted in said maindischarging chamber controlling the communication with said auxiliarychamber and having an inset tlange portion adapted to register with saiddischarge pipe, and a common controlling device for said valve and thecircuit closer, substantially as set forth.
